Outdoor Airflow Measurement

Accurate measurement of outdoor airflow is essential for the proper operation of high-performance buildings and for maintaining Indoor Air Quality (IAQ). Controlling the amount of outdoor air entering a building is necessary to maintain building pressurization, meet energy efficiency targets, verify compliance with local building codes, and protect the health of both the building and its occupants. Outdoor air can present challenges when selecting an appropriate measurement technology due to low airflow velocities, high humidity in certain climates, and the presence of airborne contaminants at the measurement point.
